Installing 69 B Body Replacement Glove Box Liner

Had anyone installed a glove box liner in a B body with the dash in the car? I pulled the cut up up original one (someone hacked in an aftermarket radio and cut the back out of it) out of my 69 Road Runner and had a heck of a time getting it out. I tried to be careful, but pretty much destroyed it removing it. I obviously need to have a bit more finesse for the installation of the reproduction I have. I've removed the upper hinge assembly and the lower latch. Are there any other tricks to getting the new one in place without damaging it? Appreciate any suggestions you folks might have for this. As always, thanks Moparts!

Go up from under & behind the dash, rear pointed upwards above the heater box, then pull forward into place.
Fuse box loose & glovebox door & hinge off as I recall...been years since I last wrestled one.

Thank you Topside!

Installing them with the dash OUT isn't easy !! Wrestling with the hinge is fun !! My advice ... take the passenger seat out so you can lay on your back when you need to.
